On having a look over it I’ve noticed that there is some lateral movement which is worrying.
It’s best shown here in this video I took:
This pic shows the set up on the non drive side:
Here is it after being dismantled:
After disassembling, picture shows from left to right:

Here is the spindle, which measures 109mm:
Bearings feel ok and show no signs of movement
I’ve got hollowgram SISL and SISL2 on other bikes and have never had an issue.
Any ideas about what's going on?
Edit: also a bb30a crankset in a BB30 frame would end up like that as the spindle is 5mm(?) longer.

Basically the shop it was purchased at hadn't torqued down the crank nearly enough so it wasn't even compressing the wavy washer. Looked like yours. Try torquing it to spec with a proper torque wrench before doing anything else. In my case that's all that was needed, at least for that issue. I also reinstalled the PF30 BB which was a creaking mess. Cleaned it up and used loctite 609 plus primer and not a problem since.
Thanks, my first thought was maybe it hadn't been tightened properly so I took it apart, cleaned it and put it back together. I don't have a 40 Nm torque wrench but it was on pretty tight, I would have had trouble tightening it any further.
I've ordered some spacers so hopefully that'll help. I'm a bit surprised thought that you need 0-3, 0.5mm spacers. Are the tolerances that variable?
This diagram shows the spacers too:
Or, one other thing to check, the spindle has a drive side and an non-drive side. One side, I believe the drive, has a longer "offset" from the bearings. There is a marking on the face of the spindle which indicates which is which. It might be in backwards.
My torque wrench that goes up to 40nm is about 18-inches long. Even with the leverage that length provides, it's pretty tough to torque to spec.
